> I opened Slack on macOS, the icon kept bouncing in the dock for a few seconds. I got impatient, switched to Ghostty, and started typing. Just then, the Slack window appeared, stole focus from Ghostty and the git pull command was sent to the group chat.

Back when I was using IRC from Emacs (with erc) I had written a safeguard in elisp against that. Haven't been on IRC in a while but this helped me prevent sending to the "group chat" (the IRC channel) a great many private infos.

Same for my real name for example: I had a filter where anything containing my actual name would be blocked.

I think a great many software where you "chat" with "groups of people" would benefit from having both default and configurable filters that catch obvious mistakes. Say you probably want a confirmation before attaching a private SSH key, or before sending a password in the clear (which could be filtered by blocking words matching the hash of the password), etc.

Not that it solves the fundamental problem TFA is talking about: nothing works.

But that is a given: that's why we need safeguards.
